Great reporting features and very functional
The solution could be more user friendly. Trying to train somebody on it can be difficult. If you're in this field, you kind of learn the tools, but trying to show a PM how to find report sheets to pull data was difficult. I had to show them how to write the queries and pull the data that they needed. It's not a layman's solution. If you're working with a programmer or with an architect, you won't have issues trying to relay how to utilize the tool. It was for those who cut the checks where there were problems enabling them to pull the data they required. I guess the answer is DevOps, but it depends on your environment. Just being able to sign into dashboards and get accurate results was my biggest thing with my PMs on my projects. They like charts and pie graphs, the ability to see things at a glance data where they could make decisions on the fly.

Data-driven experiments have transformed feature rollouts and now validate business impact
I feel that overall my experience with Split has been positive regarding necessary improvements, particularly around user experience and enhancements to the user interface, especially for larger teams. As experimentation programs grow, users must navigate many feature flags and different environments, so making discovery, organization, and lifecycle management more intuitive would be beneficial. While Split integrates well with many tools, additional connectivity with analytics and BI reporting platforms could provide a more seamless experience for organizations. There are areas where Split can be improved, particularly around advanced reporting and visualization capabilities. While the platform manages experiments and feature rollouts effectively, having more robust, out-of-the-box reporting options would allow business stakeholders to interpret results without relying on external tools. Additionally, as organizations grow, managing and overseeing feature flags becomes more challenging, so enhancing governance capabilities would be beneficial. In terms of user experience and integrations, I think the platform could enhance those areas as well. Users often need to navigate through a large number of feature flags as experimentation programs scale, so improvements to the user interface that simplify discovery, organization, and lifecycle management would be valuable, especially for larger teams. While Split integrates effectively with many tools, increasing connectivity with analytics and BI reporting could help organizations enhance their operations.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I utilized the reporting features and a number of documents, as well as statuses."
"All features are useful; our customer doesn't have any complaints about the tool, and it works pretty well for what they want and what they need to do."
"Very good reporting features."
"Split is a great way to handle the config based on checks and in a dynamic way if you want to control your software without doing any deployment."
"Split has increased some of our CVR; for example, in a recent pop-up model experiment, our conversion was around 15% and once we started the experiment, the on-variant won by increasing the CVR up to 35%, making it a really good tool for determining which particular feature would deliver the expected CVR."
"Split facilitated a culture of data-driven decision-making, allowing us to validate our ideas and providing measurable outcomes for decisions."
 

Cons

"The solution could be more user friendly."
"Its logging can be improved. When something goes wrong, it is not always very easy to find the problem. It is hard to identify whether the problem is because of low memory in the server or some configuration in Rational Build Forge. The error logs are not very detailed, and they should provide more information. It should also have more integration with third-party tools. It would be great to have more integration with third-party tools."
"Its logging can be improved. When something goes wrong, it is not always very easy to find the problem."
"Not user friendly for the layman."
"Additionally, we tend to move towards other issues related to Split due to flickering issues, which we observed because of latency."
"There are areas where Split can be improved, particularly around advanced reporting and visualization capabilities."
"The UI of split.io can be improved."
